Abstract

The invention relates to the technical field of light-emitting diode manufacturing, in particular to a light-emitting diode, a light-emitting module and a light-emitting device. The second contact electrode of the light-emitting diode is provided with two special parts with non-linear extension parts, so that an ejector pin operation window is expanded, and the problem that a chip is abnormal due to the fact that the ejector pin bursts a convex area of the contact electrode and is prone to bursting is solved as much as possible, and the problem of non-uniform light emitting of the light emitting diode caused by current change due to position change of the contact electrode can also be solved to a certain extent. Meanwhile, under the condition that the shape of the second contact electrode is guaranteed and the current distribution uniformity is improved, a current blocking layer below the extension part of the second contact electrode can be canceled, so that the voltage is reduced under the condition that the brightness is not obviously influenced, and the normal photoelectric performance of the filament lamp and the lamp strip is effectively maintained.

Description

technical field [0001] The invention relates to the technical field of light-emitting diode manufacturing, in particular to a light-emitting diode, a light-emitting module and a light-emitting device. Background technique [0002] LED filament lamps are incandescent lamps made of LEDs. In the past, to achieve a certain illuminance and illumination area, an LED light source needs to be equipped with optical devices such as lenses. On the one hand, it will affect the lighting effect, and on the other hand, it will reduce the energy-saving effect of the LED. However, the LED filament can achieve 360° full-angle light emission. , wide-angle light and no need to add a lens, it can realize a three-dimensional light source, bringing an unprecedented lighting experience. [0003] LED filaments are made by solidifying blue LED lamp beads on base strips made of sapphire, transparent ceramics, fluorescent crystals, glass, metal, etc., then connecting the base strips with gold wires, a...
